The Lowdown
G'day, it's Rusty here. Let's have a look at what's on the cards for Lakey Pipe. We've got a solid run of surf coming through, so don't go packing your bags just yet.
The pattern is a long, consistent pulse of south-west groundswell. It’s going to be a good stretch for experienced surfers, with the wave energy sitting in the strong to very strong range (1857 to 3217) for most of the first week. The water temp is sitting at a balmy 80°, which is pretty much average for this time of year, so no surprises there.
We kick things off Monday morning, September 7th. The swell is 7ft from the SSW with a 14-second period. That's a proper groundswell, and while it's got plenty of push, it's best for you guys who know what you're doing. The wind is a light cross-off from the SSE, so the waves will be clean. The wave energy is strong (1857). This sets the tone for the week.
The standout is definitely Wednesday, September 9th. The morning has 8ft of SSW swell, a long 16-second period, and a light 6 mph cross-off breeze. The combined energy is pumping hard at 3504. It's a big, powerful day – experts only territory. The wind stays light, giving you clean faces. Thursday offers a bit of a drop in size but still excellent with a solid 6ft from the SSW and a 6ft from the SW on Friday. The swell hangs in there all week with consistent sets, though you’ll want to keep an eye on the tides as the week wears on.
The following weekend, September 13th, is another winner. Sunday morning has a 6ft SW swell with an 18-second period, and by the afternoon it’s 7ft SW with the same long period and a light 6 mph breeze. The energy jumps back up to 3103, and the conditions look fantastic with clean lines.
The second week is still looking good, but a little less certain. Monday September 14th starts with a 7ft SW swell. There’s a consistent run of swell through to the 18th, all in the 5ft to 6ft range, with light winds. Keep an eye on Friday afternoon the 18th – the wind shifts to a true cross, so the surface might have a bit of texture.
The real late-show standouts are Saturday and Sunday, September 19th and 20th. Saturday afternoon sees a 8ft SW swell with a 17-second period and light 6 mph cross-off winds. The energy is strong again (3016). Sunday morning is even bigger at 8ft from the SW, with a 16-second period and the same light breeze. Up the energy to 2761. That’s a powerful weekend on the cards.
It tapers off into the final days of the forecast. Monday the 21st and Tuesday the 22nd still have fun-looking waves, with Tuesday morning bringing a smaller 3ft swell but with a *very* long 21-second period. That’s a lot of energy for a small wave, giving it plenty of shape at this reef. Because it's a reef break, that long period is a dream. Crowds are often a factor here at Lakey Pipe, so you'll want to be early or have a plan for the pack.
Rusty.

Information about the Lakey Pipe Surf forecast
The above surf forecast table for Lakey Pipe provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lakey Pipe can be found by selecting the local surf guide option on the grey menu. Our Lakey Pipe surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Lakey Pipe) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Lakey Pipe may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
